These octal bus transceivers are designed for  
asynchronous two-way communication between  
data buses. These devices transmit data from the  
A bus to the B bus or from the B bus to the A bus,  
depending on the logic level at the direction-  
control (DIR) input. The output-enable (OE) input  
can be used to disable the device so the buses are  
effectively isolated.
